nant-nanars@ i To al? 'whom it may concern Beit known that I, CARL A. Snnnnenno, a citizenof the United States, residing at Elgin, in the county of nois, have linvent/ed new and useful lnk provernents in BallLBearings, of which the following is a specification.

The` 1nvention relates to ball bearingsi held in a novel man-y wherein the balls are ner to minimize friction and to assure perfect lubrication thereof, the balls being arranged for free movement without any interference with each other.

Another object of the invention is' the provision of a ball bearing wherein the balls are confined to render the bearing dustproof, the` housing for the bearing balls being of novel form for compactness and durability.

A further object ofthe invention is the provision of a bearing of this character which is simple in construction, reliable and efficient in use, and inexpensive in manufacture.

With these andother objects in view, the invention consists in the construction, combination and arrangement Aof parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended. l

In the drawing Figure l is a.l vertical transverse sectional view through a bearing constructed in accordance wit qthef invention. Fig. 2 is yvertical longitudinal sectional view thereof. Fig."3 is a side view of one of the ball disks ofthe cage.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the ball bearing comprises a hub 5 formed with a ball for receiving a sleeve 6 which is of less width provided with rabbeted side edges to, accommodate the side disks or cheeks 7 which are fastened thereto in any suitable manner, preferably by means of screws passed therethrough and detachably engaged in the said hub so that access may be had to the interibr of the latter on the removal of either disk or cheek.- The rabbeted edges form seats for the disks or cheeks so that the lat It'a'rbwill be flush with the side edges of the The disks or cheeks 7 are centrally apertured to receive an axle or shaft 8, which S ecca'tion of Letters latent.

Kane and State of lllii than the hub, the latter being:

Fatented Mil Application lled December 29, i814. erial No. 9,526.

has iitted thereon a wearing collar or bushing 9 between which and the sleeve are l0 cated the 'bearing balls and cage therefor hereinafter fully described.

The cage comprises intermediate and outer rings l0 and ll, respectively, which are disposed 4or bushing 9 and have formed in faces opposite each other of the respective rings at intervals thereof pockets l2 correspondingly shaped to and receiving the ends of bearing balls 13, which pockets intersect the -inner and cuter peripheries of the rings 10 and ll yso that the balls 13 will be exposed for travel on the bushing and sleeve, respectively. Y

Passed through the rings l0 and ll are tie bolts le which are riveted at their ends for the uniting of the said rings together to form the cage.

Disposed against the inner sides of the disks o cheeks 7 are while formed in the rings are vents 16, ,those in the intermediate ring being designed to establish communication between the pockets in opposite sides thereof, and those in the outer rings opening through the outer faces thereof and centrally of the' pockets therein so that lubricant will be fed to and from the pockets through the vent, the washers being designed to distribute the lubricant which is introduced through an oil passage 17 formed in the hub 5 and opening through the outer periphery thereof, the sleeve interiorly of thehub being formed with an aperture alining with the oil passage in the saidv hub so that the oil will be admitted to the bearing balls within the cage therein.

Wha-t is claimed is:-

l. A ball bearing comprising outer and inner revoluble members, sleeves fitted within the outer member and upon the inner member, a plurality of rings concentrically disposed about the sleeve on the inner member and having holes at intervals therein registering with each other, bearing balls interposed between the rings, the said rings being'formed with sockets communicating with the holes and receiving the bearing balls, and bolts passed transversely through 'the rings at points between certain of the bearing balls for connecting the said rings in unison, the said balls being of a size to protrude beyond the inner and outer peripheries of the rings for contact with the sleeves.-

2. A ball bearing comprising outer and inner revoluble members, sleeves fitted withfiber or felt washers l5,

concentrically about the collar inthe outer member and upon the inner member, a plurality of rings concentrically disposed about the sleeves on the inner member and having holes at intervals therein registering with each other, bearing balls interposed between the rings, the said. rings being formed with sockets communicating with the holes and receiving the bearing balls, bolts passed transversely through the rings at' points between certain of the bearing balls for connecting the said rings in unison, the said balls being of a size to protrude beyond the inner and outer peripheries of the rings for contact .with the sleeves, and cheek plates detachably connected to opposite ends of the outer member and dis- CARL A.
